Product details

Overview

TLC073ID from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) single-supply operational amplifier in SOIC-14 package, rated for −40°C to 125°C operation. It features 16 V/μs positive slew rate, 7 nV/√Hz input voltage noise, and ultralow-power shutdown mode (125 μA/channel), enabling precision signal conditioning in automotive sensor interfaces and industrial analog front-ends.

For engineers reviewing the TLC073ID datasheet, TLC073ID pinout, TLC073ID application, or TLC073ID equivalent, this page delivers verified electrical specs, thermal performance across extended temperature range, dual-channel channel isolation behavior, and real-world drive capability into 250 Ω loads - critical for audio line drivers and active filter designs requiring rail-to-rail output swing with low distortion.

Technical Context

The TLC073ID employs TI's patented LBC3 BiCMOS process, integrating a high-input-impedance CMOS front end with a high-current bipolar output stage - delivering both low input bias current (≤700 pA) and robust output drive (57 mA sourcing / 55 mA sinking). Its architecture supports stable unity-gain operation with ≥32° phase margin at 50 pF load capacitance.

Designed for single-supply systems, it operates from 4.5 V to 16 V with common-mode input range extending from 0.5 V to VDD−0.8 V and rail-to-rail output swing. The integrated shutdown control (SHDN pin) enables fast turn-on/turn-off times (0.47 μs / 2.5 μs) while reducing supply current to 125 μA per channel.

Key Specifications

Parameter	Value and Actual Design Meaning
Bandwidth	10 MHz gain-bandwidth product - supports stable closed-loop gain up to 10× at 1 MHz for anti-aliasing filters and active equalizers.
Slew Rate	16 V/μs (positive), 19 V/μs (negative) - enables clean 10 VPP output at 100 kHz without slewing distortion in pulse amplifiers.
Output Drive	±55 mA into resistive loads - drives 250 Ω lines directly without external buffers in professional audio and PLC I/O modules.
Input Noise	7 nV/√Hz at 1 kHz - preserves SNR in low-level sensor signal chains (e.g., thermocouple amplification).
Supply Range	4.5 V to 16 V single supply - compatible with 5 V, 12 V, and 15 V industrial rails without level-shifting circuitry.
Temp Range	−40°C to +125°C - qualified for under-hood automotive applications and high-temperature industrial control environments.

Pinout & Package

Package: SOIC-14 (D package), 14-pin plastic small-outline integrated circuit, 1.27 mm pitch, body width 3.9 mm, RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1	1OUT	Output of Channel 1 - capable of ±55 mA drive, rail-to-rail swing, low output impedance (0.25 Ω at 10 kHz).
2	1IN−	Inverting input of Channel 1 - high differential input resistance (1000 GΩ), low input bias current (≤700 pA).
3	1IN+	Non-inverting input of Channel 1 - supports common-mode input down to 0.5 V above ground.
4	GND	Analog ground reference - shared return path for both channels; requires low-impedance PCB connection to minimize crosstalk.
5	2IN+	Non-inverting input of Channel 2 - electrically isolated from Channel 1; enables independent dual-path signal processing.
6	2IN−	Inverting input of Channel 2 - matched offset and noise performance to Channel 1 for differential pair configurations.
7	2OUT	Output of Channel 2 - identical AC/DC performance to Pin 1; supports independent loading and feedback networks.
8	VDD	Positive supply rail - accepts 4.5–16 V; internal regulation ensures stable biasing across full temperature range.
9	1/2SHDN	Shared shutdown control for both channels - logic-high (>2 V) enables operation; logic-low (<0.8 V) disables both amplifiers.
10	NC	No internal connection - must be left unconnected; not used for thermal pad or ESD protection.
11	NC	No internal connection - floating pin; no routing or grounding required on PCB layout.
12	3OUT	Not applicable - TLC073ID contains only two operational amplifiers; Pins 12–14 are unused in this device.
13	3IN−	Not applicable - reserved for TLC075 (quad version); electrically disconnected in TLC073ID.
14	3IN+	Not applicable - functionally unconnected; presence due to shared die/package with higher-channel variants.

Key Features

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-channel, high-output-drive operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
OPA2350EA/250	Lower noise (5 nV/√Hz), lower supply current (4.9 mA/ch), but reduced output drive (45 mA) and narrower temp range (−40°C to 85°C).	Better suited for ultra-low-noise battery-powered instrumentation; insufficient for 250 Ω line driving at full swing.	Select when noise dominates over drive strength and ambient temperature stays below 85°C.
LM7332MAX/NOPB	Higher output current (80 mA), wider supply range (2.7–32 V), but higher input offset (1.8 mV max) and no shutdown pin.	Preferred for high-voltage industrial actuator control; lacks power-gating capability needed in portable or duty-cycled systems.	Select when driving heavy capacitive loads or operating beyond 16 V; avoid when shutdown functionality or low offset is mandatory.

Compared with OPA2350EA/250 and LM7332MAX/NOPB, the TLC073ID uniquely balances 10 MHz bandwidth, ±55 mA drive, 125°C rating, and integrated shutdown - making it optimal for automotive and industrial dual-channel signal chains where thermal robustness and dynamic power control are non-negotiable.

FAQ

What is the maximum output current capability of the TLC073ID?

The TLC073ID delivers 57 mA sourcing current (IOH) at VDD − 1.5 V and 55 mA sinking current (IOL) at 0.5 V above ground, verified across −40°C to 125°C. This enables direct driving of 250 Ω loads at full swing in 5 V and 12 V systems without external buffers - a key specification confirmed in the SLOS219F datasheet Section 7.5.

Does the TLC073ID support true rail-to-rail output swing?

Yes, the TLC073ID achieves rail-to-rail output swing: VOH reaches within 1.5 V of VDD and VOL drops to within 0.5 V of GND under 50 mA load, as specified in the Electrical Characteristics tables for both 5 V and 12 V supplies. This behavior is maintained across its full −40°C to 125°C operating range, enabling efficient use of single-supply headroom.

What is the function of Pin 9 (1/2SHDN) on the TLC073ID?

Pin 9 is the shared shutdown control for both operational amplifier channels. Applying a logic-low voltage (≤0.8 V) disables both amplifiers and reduces total supply current to 250 μA (125 μA per channel). A logic-high signal (≥2 V) enables normal operation. Turn-on and turn-off times are 0.47 μs and 2.5 μs respectively, as measured in the Operating Characteristics section of the datasheet.

How does the TLC073ID compare to the TLC072ID in terms of pin compatibility and features?

The TLC073ID (SOIC-14) and TLC072ID (SOIC-8) are not pin-compatible: TLC073ID includes dedicated shutdown (Pin 9) and two NC pins (Pins 10–11), while TLC072ID uses an 8-pin layout without shutdown. Both share identical AC/DC specifications, but TLC073ID adds power-gating capability and accommodates more complex PCB routing for dual-channel isolation-critical designs.

Is the TLC073ID suitable for use in automotive under-hood applications?

Yes, the TLC073ID is explicitly qualified for −40°C to +125°C operation per its I-suffix rating and has been validated in automotive sensor signal conditioning applications. Its 100 dB PSRR suppresses alternator ripple, 125°C-rated SOIC package withstands under-hood thermal cycling, and BiMOS process ensures stable offset and noise performance across temperature extremes - all confirmed in TI's SLOS219F datasheet.
